British households risk unaffordable energy bills, Ofgem warns

In a wide-ranging report into the future of Britain's energy market, Ofgem said that there is a risk that bills could rise by up to 25pc over the next decade unless measures are taken.

Ofgem said that the unprecedented combination of the global financial crisis, tough environmental targets, increasing gas import dependency and the closure of ageing power stations has combined to cast reasonable doubt over whether the current energy arrangements will deliver secure and sustainable energy supplies.
